In thermodynamics, a process is called reversible when

A

the system changes into the surrounding spontaneously

B

the surrounding are always in equilibrium with the system

C

there is no boundary between and surrounding

D

surroundings and system change into each other

Text Solution

Verified by Experts

The correct Answer is:
B
During a reversible process in themodynamics, the system and its surrounding are more or less in equilibrium because th process is carried out infinitesimally very slowly.
